We have to analyze the scope of incisor caries in general, because the occlusal relationship of each patient is different, we have to consider what kind of occlusal relationship it is, for example, the patient is a normal occlusal relationship, the area of defect is not very big, not more than 1/2, or there is only one incisal defect. In this case do porcelain veneers very good. There is another problem, if the tooth is dead pulp teeth, such as incisors killed the nerve, when doing porcelain veneers, to take into account the later affected teeth will change color, to choose a different type of porcelain veneers. Porcelain veneers are divided into porcelain veneers, and cast porcelain veneers, which are often done. Porcelain veneers have a stronger refractive effect. Cast porcelain veneers, with better permeability, are slightly less refractive. So depending on the condition of the affected tooth, different types of porcelain veneers are chosen. If the tooth is living pulp, the color does not matter, you can choose different prices of porcelain veneers or cast porcelain veneers can be. If the affected tooth is the case of anti-jaw bite, according to the anti-jaw situation anti-jaw has 1 degree, 2 degrees, 3 degrees, can be divided into various cases to determine whether you can do all-porcelain crowns. Not all incisors can do porcelain veneers if they are bad later. If there is only a residual root left, you may need to pile up a full crown instead of porcelain veneers.
